Hello,

I am currently using the Dspace 6.3 JSPUI interface, the client side system works normally, I can access all pages and submissions.

However I have been receiving several error emails with the information of "Broken pipe" or "java.net.SocketTimeoutException" and could not identify the root of the problem.

Any help is most welcome.

Thanks!
